IBL in other mathematics courses

While the focus of this project is on college-level mathematics courses for students in the liberal arts, our experience and expertise with the pedagogy of Inquiry-Based Learning extends far beyond this specific focus. We all routinely teach the full range of college-level mathematics courses with an inquiry-based approach with strong success: lower-level undergraduate mathematics courses including Calculus I-III, upper-level math major courses focusing on proofs, and content courses for future elementary and secondary teachers. We also work with K-12 teachers in bringing IBL techniques into their classrooms.

Do you think it is possible to teach calculus without ANY lecture? (or any other passive teaching method like watching videos, reading the book etc.) Well, I have been teaching calculus (I, II and III) for the last 7 semesters doing just that. And I love it.
